Specification of Letters Patent.

Patented Nov. 22, 1910:

v Application filed Iay 12,191l). Serial No. 561,024. 1

To all whom it-may concern:

Beit known that I, Enson C. Cove'in', re-

siding at New Kensington, in the county of- West-moreland and State ofPennsylvania,

have invented a certain new and useful Im-" .proven 1ent 1n MetallicCarlines, of which the following is 'a full, clear, and exactdescription, reference being had to the accompany ing drawings, whichform part of this specification.

This invention relates to metallic carlines for box and similar cars,and has for its primary object to, provide a construction which for thesame weight of material will give greater -strength thanis present.inthis member as'heretofore constructed.

It also aims to provide other details of construction, as will behereinafter more fully described. u y

I will now describe my invention, referring toi theaccompanyingdrawings, so that.

others skilledin the art to which it appertains' may understand andconstruct the same.

Figure 1 is a vertical section through a box car showing my improvedcarline applied thereto; Fig. 2 is a section of the carline taken on theline-22 of Fig. 1; Fig. 3 is a similar view taken on the line 33 of Fig.1; and Fig. 4 isa side elevation of the end of the carline; showingmodified end construction.

In the drawings the reference numeral 2 indicates the siding, 3 the sideplates, t a carline, 5 the purlins and 6 the roofing of a box car.

My 'carline comprises the channel member 7 arranged so that the flanges8 project up ward and is bowed to take the shape ,of the roof. The webportion 9, projecting beyond the flanges 8 at each end of the carline,is turned down, forming the flanges 10 by means of which the cal-linemay be bolted or otherwise fastened to the side plates 3 of the car. Tostrengthen this channel shaped carline against deflection underoperative stresses, I form in the web portion 9 thereof,

the substantially U -sh.aped depression orreinforcing flute 11, whichprojects preferably in a direction opposite'to that of the flanges8',"-thus forming, in combination with these flanges, a trussedconstruction which effectually meets the stress conditions of me- Atallic carline's. This depression 11 may feather 01f at each'end as itapproaches the respective ends of the carline, as shown in Fig. l, ormay extend from end to end of'the body of the carline, as shown in Fig.4, and

indicated by the numeral 11'; the two arrangements not affecting thestrength of the truss but merely presenting differently shapedendibolting flanges. At suitable intervals alongthe carline, the depressionor flute 1-1' is square finished or bossed as indicated bythe; numeral12, so as to-afiord appropriate seats for the head or nut of thefastening means 13 of the purlins 5. /A wood filler 14-, mounted betweenthe flanges of the carline presents suitable fiat seats for thepui'lins. This wood filler, however, in

the absence of pu'rlins; also serves as a nailing strip for the roofboards or plates of the car. I

I prefer to construct my improved carline from a channel member ofconventional cross section. The distribution of material in the ordinarycommercial or conventional rolled channel section being such as toprovide greaterthickness of metal in the flanged portions than intheweb, with the web portion reinforced as in my improved carline thereis presented a light weight construction capable of meeting the maximumroof stresses. I find under test, that my invention increases thestrength of the ordinary channel carline 300 per cent.

-The advantages of my invention will be appreciated by those skilled inthe art.

It will be apparent that many changes may be made in the constructionshown which would not be a departure from my invention, and I do nottherefore desire to limit myself theretofi Having thus described myinvention, what I claim and desire to secure by Letters Patent is:

1. A metallic carline embodying a conven- 'tional rolled channel sectionhaving formed in the web portion thereof a. longitudinal corrugation.

' 2. A metallic carline embodying a conventional rolled channel sectionhaving a substantially U-shaped longitudinal corrugation formed in itsweb portion,' and projecting in a direction opposite to that of the 105flanges. In testimony whereof, I have hereunto set my hand.
